Application iled February 2, 1903. Serial No. 141,562. (No modelilf Toall whom, t may concern:

Be it known that LBERN'HARD H. NOELTING,

a citizen of the UnitedStates, residing at Nebraska City, in the countyof Otoe and State `of Nebraska, have invented certain new and usefulImprovements in Casters and Sockets; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

My invention is an improvement in casters and sockets-that is, it is animprovementin casters generally as understood in the trade, whichincludes both the caster and socket, as my invention isV the combinationof the two; and it consists of a socket made of one piece of sheet metalso shaped, perforated, cnt, and folded as to make a spring-socket,together with a bracket made of one piece of metal so shaped, stamped,and bent as to cooperate with the socket, with a pintle secured in thebracket and working in the socket.

In the accompanying drawings, Figurelis a plan View of the sheet ofmetal out of which the socket is made after theiirstoperation. Fig. 2 isa similar view of the same piece of metal after the second operation.Fig. 3 is a sectional view of Fig. 2. Fig. 4: is a plan view of the saidsheet of metal after the fourth operation. Fig. 5 is a sectional view ofFig. 4E. Figs. 6 and 7 are frontand side views of the socket after it isformed. Fig. 8 is a vertical sectional view of Fig. 6. Fig. 9 is asideelevation of the bracket. Fig. 10 is a front elevation of the same, oneof the legs being in section to better show the drawn perfora-l tionnear the end of the leg. Fig. ll is a side elevation of the socket,bracket, and pintle,

the socket being lin section.

My invention is described as follows:

1 is a face View ofthe plate provided with two end perforations 2 and acentral perforation 3, and near each end'of the plate are cut arms 4,which include the said perforations 2, and these arms are bent upwardlyand at right angles to the face of said plate. The

lower ends, however, of these arms while attached to the said plate andintegral there# with -leave openings 5. There are therefore left oneither side of said-openings parts 6 of said plate, which when properlybent form springs. I call them springs because these parts 6 are bowedoutwardly and when forced up into the foot or leg of abedstead or othersimilar piece of furniture on 'account of their resiliency hold the saidsocket in place, so that it will. not drop out when the furniture isbeing moved. After reaching this point in the evolution of my socket itis then stamped untileach end is semicircular in shape. The center isstruck down, forming a track-plate 7, and the perforated part 3 isstruck or drawn up, forming a neck 8, and each edge of the track-plateis also struck'up, forming two recesses 9. These recesses 9 are for thepurpose of strengthening the track-plate, and the neck 8 of theperforation 3 is for the purpose of giving such a bearing for the pintlethat it may turn easily and may not be cnt in the operation of turning.The two ends.v of the plate are then bent at the points lO-upwardly atright angles to the track-plate and until the two arms't overlap eachother and until the perforations 2 register with each other. The socketis then complete. The track-plate 11 of the bracket is struck up in itscenter, f

forming a washer 12. This washer hasin its center a perforation 13 forthe accommodation of the pintle 14, in which perforation the pintle isrigidly and'securely fastened. The legs 15 are bent downwardly and runrearwardly at an angle vof about forty-five degrees to the face ofthetrack-plate, and each foot has inV its lower end a perforation 16, whichis drawnthat is, thevm'etal at the lower end of said feet is pressedoutwardly, forming a raisedpart 17, and then inwardly,

forming a neck 18, which gives a smoothV IOO revolving of the pintle andprevents the pintle from being cut in this revolution. The recesses 9 ofthe track-plate make Walls that are practically at right angles to thetrackplate, and thereby strengthen it very much. 'lhe circular shape ofthe end pieces gives strength to the same, and at the same time, theparts that are cut out, leaving the openings 5, give to the walls of thecaster springs G. The perforated arms 4 are integral With the outer endsof the plate 1, and therefore are much stronger than if riveted andWelded into the same. The raised part 12, of the bracket 15, produces awasher insuring an easy turning of the bracket under the caster, and thedrawing ofthe perforations 16, in the feet, give a broad surface to thebearings, and thereby insure easy revolution of the roller 20, andprevent the axle of the roller from being cut.

Having described my invention, what 1 claim as new, and desire to secureby Letters Patent, is-

1. The combination of a caster, consisting of a plate 1, provided with acentral perforation 3, and neck 8; arms 4, cut from each end of the saidplate, and provided with perforations 2; said plate having in itscenter-,a trackplate, provided with recesses 9; the two ends of saidplate bent upwardly at right angles to the track-plate, until the arms4, overlap each other, and the perforations2, register; a bracket 15,provided with an elevation l2, on the upper face of its track-plate, anddrawn perforations in its feet, producing iiattened bearings 19; apintle 14, securely fastened in the center of the said elevation 12, andpassing up through the perforations 2, in the arms 4, and secured, and aroller 20, journaled between the feet of said bracket, substantially asshown and described and for the purposes Set forth.

2. In a castel', a socket, consisting of a plate 1, provided with acentral perforation 3, and neck S; arms 4, cut from each end of the saidplate, and provided with perforations 2; said plate having in itscenter, a track-plate provided With recesses 9; the two ends of saidplate bent upwardly at right angles to the track-plate, until the arms4, overlap each other, and the perforations 2, register; substantiallyas shown and described and for the purposes set forth.

3. In a caster, a bracket 15, provided with an elevation 12, on theupper face of its trackplate, and drawn perforations in its feet,producing ilattened bearings 19; a pintle 14, securely fastened in thecenter of the said elevation 12, and passing up through the perforations2, in the arms 4, struck up from the ends of plate l and secured, and aroller 20, journaled between the' feet of said bracket, substantially asshown and described and for the purposes set forth.

4. In a caster, a socket consisting of a plate 1, provided with acentral perforation 3; a central neck 8, and arms 4, having perforations2; a track-plate 7, having recesses 9; springs 6, formed from the wallsof said socket, the ends of said plate made cylindrical, and bent up'until said arms overlap each other, and until said perforations 2,register, substantially as shown and described and for the purposes setforth.

5. In a caster, the combination of a trackplate 11, a perforated washer12, raised on the upper face of said track-plate; a pintle 14, firmlysecured in the perforation of said Washer; legs l5, extending downwardlyfrom said track-plate; drawn perforations in the feet of said legs,forming broad bearings 19, and a roller journaled between said feet,substantially as shown and described and for the purposes set forth.

In testimony' whereof l affix my signature in presence of two witnesses.
